An Egyptian leftist opposition group urged its supporters to head to the presidential palace on Wednesday in response to the Muslim Brotherhood's call for a protest there in support of President Mohamed Mursi, a spokeswoman said.

Founded in 1968, the Brotherhood Crusade 's principal mission is dedicated to building and sustaining an institution that raises funds and resources from within the community and distributes those funds directly back into the community.

In science:

To analyze the throughput loss, we model coding over generations with random generation scheduling as a coupon collector’s brotherhood problem.

Effects of the Generation Size and Overlap on Throughput and Complexity in Randomized Linear Network Coding

Section IV introduces the coupon collector’s brotherhood problem and its variations that can be used to model coding over generations.

Effects of the Generation Size and Overlap on Throughput and Complexity in Randomized Linear Network Coding

The algorithm is based on the analysis of the overlapping structure in Section VI-B and the results from the extended collector’s brotherhood in Section IV.

Effects of the Generation Size and Overlap on Throughput and Complexity in Randomized Linear Network Coding

The coupon collector’s brotherhood problem , studies quantities related to the completion of m sets of n distinct coupons by sampling a set of n distinct coupons uniformly at random with replacement.

Therefore, we must generalize the coupon collector’s brotherhood model from collecting a uniform number of copies for all coupons to collecting different numbers of copies for different coupons, before it can be applied to the analysis of the throughput performance of coding over generations.

In this section, the original collector’s brotherhood model is generalized in two ways.

In the following, we present another generalization of the collector’s brotherhood model.
